    Abstract

    This paper presents a zero-knowledge interactive protocol that demonstrates two factors a and b of a composite number n(= ab) are really known by the prover, without revealing the factors themselves. Here the factors a and b need not be primes. The security of the protocol is based on the difficulty of computing discrete logarithms modulo a large prime.
